SPECFICATION forming part of Letters Patent No. 399,199, dated March 5, 1889..

Application tiled April 7, 1888. Serial No. 270,004. (No model.)

To f1/ZZ whom t muy concern:

Be it known that I, WILLIAM REGLER, a citizen ot the United States, residing at Bellevue, in the county of Jackson and State ot Iowa, have invented certain new and useful Improvements in Pumps; and l do hereby declare the. following to be a full, clear, and exact deseriptifm ot the same, reference being had to the annexed drawings, making part of this specification.

This invention relates to improvements in chain-pumps, and has for its object the construction et metallic tubes coupled together to torni a pump-steek for chain-pu1nps, said tubes to have abutting flanges held firmly against an intervening leather or rubber gasket by ineens et' thiinble-(ieouplings bearing against the back sides et' said flanges; also, said pipes are so constructed as te form in the seam an interior groove or backwater-passage running the whole length of each pipe, the object et said groove being to let the water settle back into the well or cistern when the operation et pumping has ceased. lTurthermore, the seam thus made in the pipes affords an external rib or flange, which enters into a mnresponding seat or recess in the interior ot' the thiiubleeouplings to prevent them turning on their respective pipes, also, an inverted-funnel-shaped ring is soldered or otherwise secu red to the lower end of the pipe, te prevent the buckets trom catching upon the end ot the tube.

in the drawings, Figure l is a vertical section of my improved pump-tubes, with their tlanges, the couplingthimbles, leather gasket, and tunnel-ring at the bottom. Fig. 2 (exclusive ot the dotted circle) is a transverse section on the line iny in Fig. l.,which also eoincides with line m in this figure. Fig. 3 is a vertical section cutting the broken line n n in Fig. Fig. 2 (excluding the dotted circle) also built on the line n in Fig. 3, but including the dotted circle it is built on the line `n' in Fig. 3.

A and l represent two lengths of metallic tubing; C,the upper coupling-thixnble,and C thelower; d, the gasket; c, the abutting AFla-nge on the pipe ends; F, the funnel-ring; j, the

In Fig. 2 the form ot' the seam is represented, showing' the groove or ba ckwaterpas Sagey and the inode of interlocking the two edges ot the pipe so as to forni the groove in the seam. By the use of this groove I am enabled to use close-iitting buckets having no water passage-ways, as heretofore used, through which to let the water settle back into the well after the pumping has ceased. The seam is then soldered either inside or outside, or both, as may be desired.

For a little distance upward from the lower end of the tube l expand it so as to admit of a slight projection inwardly oi the face of the funnel-ring F beyond the inside surface ot the tube, as shown at o, where the ring and pipe are soldered together, the projection being made in order to protect the solder, and the expansion in order to Secure uniformity of size between the ring and the pipe a little distance from the ring. The groeve in the pipe is continued straight down tl'irough the inner :tace of the ring,

Bythe use ot my grooved pipe a far cheaper bucket may be used-one that will not require frequent expansion or attent-ion of an y kindand as the pipe is made ver;` smooth inside a solid bucket will wear a long time without renewal, iitting the pipe close enough for all vpractical purposes, and yet permitting the water to setlle back through the groove j quick enough to prevent freezing in. winter or becoming warm in summer.

The main object et the backwater-groove 7' is to do away with the hitherto practice of opening a channel through. the buckets to let the water settle through an d. to avoid the expense of expansion-buckets 110W n common the inverted-funnel ring F, all Constructed use. substantially as and for the purposes set I 01mmforth. In a chain-pump, the combination of the v TILLIAM KEGLER. 5 metallic flanged tubes A and B, having the Attest:
